Rocks & Gems: An Exploration

By Julia Silverman & Leah Zhang  

Today we will show you five rocks, Amethyst, Obsidian, Green Fluorite, Yellow Tiger’s Eye, & Moonstone. So basically, we will take a poll, asking you which ones do you like the best? Then we will interview five people, asking them why they chose that rock/gem. We will also add a facts page, & we’ll also show you the results.  😉  

Let’s talk facts about the rocks & gems.

First up is Amethyst.  

Amethyst is a type of quartz. Amethyst is also the birthstone of February, the official gemstone of Wednesday & the 6th & 7 tenth wedding anniversary. You can usually find them in Brazil & Uruguay.  

Obsidian, yes, in Minecraft, but wait. There’s more. Obsidian ONLY forms near volcanoes. Seventy percent of Obsidian rock is silica. The best Obsidian is formed underground near a volcanic vent because those rocks will have limited impurities. You can usually find them in North Carolina & the eastern part of Virginia.  

Green Fluorite is also called Fluorspar, made-up of a mineral called calcium & fluoride also known as calcium fluoride. Fluorite is colorless, only colored because it has various impurities, usually found worldwide but especially China & South Africa.  

Yellow Tiger Eye is a Planetary stone for Gemini (May 21-June 20) & the official gem for the ninth wedding anniversary. It is also a member of the Chatoyant family, and Chatoyancy is a changeable silky luster when light reflects on it, within the thin parallel, fibrous bands. This effect is because of the fibrous structure of the material.  It’s often found in India.  

Finally, we have Moonstone! Moonstone comes in many different colors: white, grey, green, pink, blue, purple, orange, brown, and yellow. It is a sodium potassium aluminum silicate of the feldspar group, displaying a pearly & opalescent Schiller. You could also call it Hecatolite, found in Europe’s southern Alps.  

            Results: 

As you can see Amethyst was first, Green Fluorite was second, Obsidian was third, and Moonstone and the Tiger Eye tied for fourth and fifth. 

Interviews: 

We interviewed 5 people that voted. Here’s what they said: 

Mrs. Morrison chose green fluorite because she says: “It reminds me of the ocean.” (Deep green color)  

Samantha chose Moonstone because she says:” It reminds me of the Moon, which has always been a symbol of peace.”  (Shiny pearly white with a hint of grayish pearly color.) 

Nancy chose ameythst because she says: “It’s pretty and cool” 

Will chose obsidian because he says: “I like it because it’s in Minecraft” (a shiny black) 

Leah chose tiger eye because she says: “I liked the stringy-umbrae affect.” (brown-yellow umbrae)
